The sensor has a first emitting source, to either emit onto, or from the object, a first receiving sensor, to receive emissions from the first emitting source, either directly or indirectly, the emissions received dependent on said angle, first receiving sensor outputting a first signal a course measurement of the angle. Also present is a second emitting source, to emit onto, or from the object and a second receiving sensor, to receive emissions from the second emitting source, either directly or indirectly the emissions received again dependent on said angle, second receiving sensor outputting a second signal, as a fine measurement of the angle. A method of use of the sensor is disclosed together with a method of combining the fine and course measurements to output a signal with zero error."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotational sensor and methods therefor","description":"The invention is a rotational sensor to sense an object's angle and methods to analyze the sensor output.
